[PATCH v2] drm/bridge/synopsys: dsi: add optional pixel clock

2018-01-12 Thread Philippe Cornu
The pixel clock is optional. When available, it offers a better preciseness for timing computations and allows to reduce the extra dsi bandwidth in burst mode (from ~20% to ~10-12%, hw platform dependent). Signed-off-by: Philippe Cornu --- Changes in v2: Improve px_clk probing in case of ENOENT d
